[0027] The existing test bench does not have an adjustment structure, which means that the wind turbine gearbox needs to be continuously adjusted by the machine to be accurately installed during installation, which is very troublesome. The inaccurate position is very unfavorable for the test of the wind turbine gearbox 16. The limiting mechanism 5 includes a support plate 51, which is fixedly connected to the middle part of the support plate 51 and the fixed plate 12. The upper end of the support plate 51 is rotatably connected to the gear 52, and the upper end of the gear 52 is fixedly connected to the first threaded rod 53. The upper end of the first threaded rod 53 is threadedly connected to the limiting tube 54.

[0028] The limiting tube 54 is fixedly connected to the limiting plate 55 on one side close to the fixed plate 12. The limiting plate 55 and the fixed plate 12 are slidably connected. A marking line is provided on the fixed plate 12 to facilitate staff to observe the position of the limiting plate 55 moving on the fixed plate 12.

[0029] The gear plate 8 drives the gear 52 to rotate, the gear 52 drives the first threaded rod 53 to rotate, and the first threaded rod 53 drives the limiting tube 54 to move, so that the limiting tube 54 drives the limiting plate 55 to slide on one side of the fixed plate 12. The staff can judge the position of the wind turbine gear box 16 driven by the movable ring 43 by observing the position of the limiting plate 55 moving on the fixed plate 12, thereby playing a role in positioning and adjustment.

[0030] In order to facilitate the movement and adjustment of the wind turbine gearbox 16 on the experimental bench 1 and to facilitate the connection of the wind turbine gearbox 1 with the simulated speed measuring equipment 2, the adjustment mechanism 4 includes a servo motor 41, and the servo motor 41 is fixedly installed in the experimental bench 1.

[0031] The servo motor 41 drives the second threaded rod 42 to rotate, and the second threaded rod 42 drives the moving ring 43 to move, so that the moving ring 43 drives the support base 44 to move, and the support base 44 drives the upper wind turbine gear box 16 to approach the simulation speed measuring device 2.

[0032] The support base 44 is fixedly connected to the gear plate 8 near the side of the gear 52. The gear plate 8 can engage with the gear 52, so that the gear plate 8 can drive the gear 52 to rotate, and the gear 52 can drive the first threaded rod 53 to rotate.

[0034] Example 2

[0035] See also Figure 1 、 Figure 2 and Figure 5 , further improvements were made on the basis of Example 1:

[0036] In order to facilitate the stable fixation of the wind turbine gearbox 16 on the support seat 44, and enable the clamping plate 13 to clamp the wind turbine gearbox 16, thereby facilitating the installation of the wind turbine gearbox 16, the installation mechanism 6 includes a turning handle 61, one side of the turning handle 61 is fixedly connected to the third threaded rod 62, and both sides of the third threaded rod 62 are threadedly connected to the adjusting ring 63, the upper end of the adjusting ring 63 is fixedly connected to the clamping plate 13, the upper end of the clamping plate 13 is respectively installed with the first connecting rod 14 and the second connecting rod 15, and the second connecting rod 15 is closer to the analog speed measuring device 2, the clamping plates 13 are all square, and the clamping plates 13 are adapted to the wind turbine gearbox 16.

[0037] Install the wind turbine gearbox 16 on the support seat 44, and make the two clamping plates 13 located on the outer plate of the wind turbine gearbox 16, then rotate the handle 61 to make the handle 61 drive the third threaded rod 62 to rotate, and the third threaded rod 62 drives the two adjusting rings 63 to move, so that the two adjusting rings 63 drive the clamping plates 13 on the same side to approach each other and clamp the wind turbine gearbox 16, so as to facilitate the fixation of the wind turbine gearbox 16.

[0038] In order to ensure the stability of the two clamping plates 13 and avoid accidental touching of the handle 61, which may cause the clamping plates 13 to move, the first connecting rod 14 is fixedly connected to the plug-in frame 17 on the side close to the second connecting rod 15, and the upper end of the plug-in frame 17 is fixedly connected to the elastic member 18, and the upper end of the elastic member 18 is fixedly connected to the clamping block 19, which is clamped to the second connecting rod 15.

[0039] The first connecting rod 14 and the second connecting rod 15 are close to each other, and the insertion frame 17 on the first connecting rod 14 enters the second connecting rod 15. During the entry process, the clamping block 19 is squeezed and contracted by the inner wall of one side of the second connecting rod 15 and enters the insertion frame 17, causing the elastic member 18 to contract. When the insertion frame 17 is fully inserted into the second connecting rod 15, the elastic member 18 drives the clamping block 19 to recover, and causes the clamping block 19 to clamp the second connecting rod 15, so that the two clamping plates 13 are fixed, and the clamping plate 13 is fit with the outer plate of the wind turbine gearbox 16.

[0040] By using the installation mechanism 6 to drive the two clamping plates 13 to move, the clamping plates 13 are fixed to the wind turbine gearbox 16, making the wind turbine gearbox 16 more stable during adjustment and installation, and a clamping block 19 and a clamping frame 17 are provided to clamp the second connecting rod 15, so that the two clamping plates 13 can be connected and fixed, avoiding the shaking of the clamping plates 13 affecting the test of the wind turbine gearbox 16.

[0041] Example 3

[0042] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , further improvements were made on the basis of Example 2:

[0043] In order to protect the simulated speed measuring device 2 on one side of the test bench 1 and prevent the support seat 44 from driving the wind turbine gearbox 16 to move, causing it to be too close to the simulated speed measuring device 2, the fixed plate 12 is fixedly connected to the protection rod 10 on the side close to the limit mechanism 5, and the protection rod 10 is fixedly connected to the second spring 11 on the side away from the fixed plate 12. The second spring 11 is fixedly connected to the protection tube 9 on the side away from the protection rod 10, and the protection tube 9 and the support seat 44 are fixedly connected.

[0044] When the support seat 44 drives the wind turbine gearbox 16 to move, the support seat 44 will push the protective tube 9, causing the protective tube 9 to push the second spring 11 and approach the protective rod 10, so that the protective rod 10 and the protective tube 9 can prevent the support seat 44 from continuing to move forward and alert the staff.

[0045] An ejection mechanism 7 is installed on the upper end of the second connecting rod 15 near the first connecting rod 14. The ejection mechanism 7 includes a protective frame 71. The protective frame 71 is slidably connected to a pressing plate 72 near the first connecting rod 14. The middle part of the lower end of the pressing plate 72 is fixedly connected to a first spring 73. The lower end of the first spring 73 is fixedly connected to the second connecting rod 15. The lower end of the pressing plate 72 is fixedly connected to a pressing block 74 away from the protective frame 71. The pressing block 74 is located directly above the blocking block 19.

[0046] When the two clamping plates 13 need to be separated and the wind turbine gearbox 16 needs to be disassembled, the pressing plate 72 can be pressed to squeeze the first spring 73 and drive the pressing block 74 to descend, so that the pressing block 74 squeezes the clamping block 19 located directly below it, so that the clamping block 19 enters the clamping frame 17, and then the turning handle 61 is turned to move the two clamping plates 13 away from each other.

[0047] The specific method of use is: install the wind turbine gearbox 16 on the support seat 44, and make the two clamping plates 13 be located on the outer plate of the wind turbine gearbox 16, then rotate the handle 61, so that the handle 61 drives the third threaded rod 62 to rotate, and the third threaded rod 62 drives the two adjusting rings 63 to move, so that the two adjusting rings 63 drive the clamping plates 13 on the same side to approach each other and clamp the wind turbine gearbox 16, at the same time, the first connecting rod 14 and the second connecting rod 15 are close to each other, and the insertion frame 17 on the first connecting rod 14 is inserted into the second connecting rod 15. During the entry process, the card block 19 is squeezed and contracted by the inner wall of one side of the second connecting rod 15 to enter the card block 17, and the elastic member 18 is contracted. When the card frame 17 is fully inserted into the second connecting rod 15, the elastic member 18 drives the card block 19 to recover, and makes the card block 19 clamp the second connecting rod 15, so that the two clamping plates 13 is fixed, and the clamping plate 13 is fitted with the outer plate of the wind turbine gear box 16, and then the servo motor 41 is started, so that the servo motor 41 drives the second threaded rod 42 to rotate, and the second threaded rod 42 drives the moving ring 43 to move, so that the moving ring 43 drives the support seat 44 to move, and the support seat 44 drives the upper end of the wind turbine gear box 16 to approach the simulation speed measuring device 2. At the same time, the support seat 44 drives the gear plate 8 to move, and makes the gear plate 8 approach the gear 52 and engage with it, the gear plate 8 drives the gear 52 to rotate, and the gear 52 drives the first threaded rod 53 to rotate, and the first threaded rod 53 drives the limiting tube 54 to move, so that the limiting tube 54 drives the limiting plate 55 to slide on one side of the fixed plate 12. The staff observes the position of the limiting plate 55 moving on the fixed plate 12 to judge the position of the wind turbine gear box 16 driven by the moving ring 43, which plays a role in positioning and adjustment.
